Objective To investigate and analyze epidemiological characteristics of patients with mycoplasma pneumoniae pneumonia (MPP) from 2020 to 2023, and the risk factors for plastic bronchitis (PB), To provide data support for developing preventive measures. Methods The medical records of 2 257 patients with respiratory tract infection treated at Huai'an Hospital Affiliated to Xuzhou Medical University from 2020 to 2023 were collected. Count the number of MPP patients and analyze the MP detection rate. Multivariate logistic regression analysis and ROC curve was used to screen the risk factors for PB. Results A total of 858 cases were positive for MP antibodies, and the detection rate was 38.02%. There are statistically significant differences in MP detection rates among different genders, age groups, and years (P<0.05). Among the 286 patients diagnosed with MPP and undergoing bronchoscopy, 68 (23.78%) patients had PB. According to univariate and multivariate logistic regression analysis, small age, higher N%, D-D, LDH and AST levels were independent risk factors for PB (P<0.05). ROC curve analysis shows that age and combined detection are the most effective indicators for PB prediction, with areas under the curve of 0.998 and 0.961, respectively. Conclusion MP is the main pathogen of respiratory tract infections in the area from 2020 to 2023. Women and children are more susceptible to MP infection. Small age, high N%, DD, LDH and AST levels are independent risk factors for PB in patients with MPP. Targeted preventive measures should be taken for MP susceptible population, and close attention should be paid to PB related risk factors to prevent disease progression and the occurrence of PB.

Objective: To explore the relationship between the ratio of dietary vitamin A (VitA) to body weight and hypertension among children, so as to provide a reference for blood pressure control through dietary nutritional interventions and childhood hypertension prevention. Methods: Utilizing the baseline survey and followup sample data from the Healthy Children Cohort established in urban and rural areas of Chongqing from 2014 to 2019, structured quantitative dietary questionnaire and selfdesigned questionnaire were used to investigate the information of dietary intake and socioeconomic characteristics of 15 279 children, as well as blood pressure, height, weight measurement. The ratio of dietary VitA to body weight was divided into four groups based on quartiles [≤P25(Q1), >P25~P50(Q2), >P50~P75(Q3), >P75(Q4)]. Generalized linear regression models and Logistic regression models were used to analyze the correlation between ratio of dietary VitA to body weight with blood pressure levels and prevalence of hypertension. Results: The results of the 2014 baseline survey indicated that, after adjusting for confounding factors such as demographic indicators and nutritional intake, significant differences were observed in systolic blood pressure (SBP), diastolic blood pressure (DBP), and mean arterial pressure (MAP) among different groups categorized by the ratio of dietary VitA to body weight (F=157.57, 44.71, 95.92, P<0.01). The baseline ratio of dietary VitA to body weight in children exhibited a negative correlation with DBP, SBP and MAP at baseline and in 2019[baseline: β(95%CI)=-0.65(-0.89--0.42), -0.22(-0.42--0.01), -0.36(-0.56--0.16); 2019: β(95%CI)=-0.77(-1.34--0.19), -0.62(-1.21--0.02), -0.77(-1.34--0.19), P＜0.05]. Compared to Q1 group, the risk of hypertension decreased among children in Q4 at baseline and followup in 2019 [OR(95%CI)=0.63(0.49-0.81), 0.18(0.08-0.42), P<0.01]. Conclusions The ratio of dietary VitA to body weight is significantly negatively correlated with blood pressure levels among children, and dietary VitA deficiency is an independent risk factor for hypertension among children. Measures should be taken to actively adjust childrens dietary nutrition and reduce the risk of childhood hypertension.

Background::Evaluating the impact of digestive system diseases is vital for devising effective prevention strategies. However, comprehensive reports on the burden of digestive system diseases in China are lacking. Our study aimed to provide an overview of the burden and trends of digestive system diseases from 1990 to 2019 in China and its provinces.Methods::This cross-sectional study utilized the Global Disease Burden Study 2019 to estimate the incidence, mortality rate, disability-adjusted life years (DALYs), years of life disability, years of life lost, and changes in the burden of digestive diseases across Chinese provinces from 1990 to 2019. The analysis of disease burden primarily examines the characteristics of sub-disease distribution, time trends, age distribution, and sex distribution. Additionally, we compared provincial age-standardized DALYs for digestive diseases with the expected rates based on the socio-demographic index (SDI).Results::In 2019, there were 499.2 million cases of digestive system diseases in China, resulting in 1,557,310 deaths. Stomach cancer, colon and rectal cancer, and esophageal cancer are the top three diseases associated with mortality and DALY related to digestive system diseases. Meanwhile, cirrhosis and other chronic liver diseases, gastroesophageal reflux disease, and gallbladder and biliary diseases are the top three kinds of diseases with the highest prevalence among digestive system diseases. The risk of gastric cancer sharply increases among men after the age of 40 years, leading to a significant disparity in burden between men and women. As the SDI increased, the DALYs associated with digestive system diseases in China and its provinces showed a downward trend.Conclusion::Our study highlights the inverse correlation between DALYs associated with digestive system diseases and the SDI.

Abstract：Objective To improve the replication level of varicella⁃zoster virus（VZV）in human diploid cell line MRC⁃5 and increase the yield of VZV vaccine by reducing the expression of interferon（IFN）related genes via optimizing the cell line MRC⁃5. Methods Interferon receptor 1（IFNAR1）silenced MRC⁃5 cell line（MRC⁃5IFNAR1⁃）was constructed by CRISPR／Cas9 gene editing technology，which was determined for the relative expression of IFNAR1 mRNA，and for those of mRNA of IFN related genes IFNβ and OAS1 after VZV infection by qRT⁃PCR to evaluate the effect of gene silencing. Gene mutation sequences were further identified by sequencing of the silenced sites. The replication of VZV in MRC⁃5 and MRC⁃5IFNAR1⁃ cell lines was compared 168 h after VZV infection by using qRT⁃PCR and plaque formation unit（PFU）assay， to evaluate the effect of MRC⁃5IFNAR1⁃cell line on VZV replication. Results The growth status of MRC⁃5IFNAR1⁃ cell line wasconsistent with that of MRC ⁃ 5 cells，and the relative expression of IFNAR1 mRNA decreased by 73%；The relative expressions of IFNβ and OAS1 mRNA in MRC⁃5IFNAR1⁃ cell line were 61% and 90% lower than those in MRC⁃ 5 cells respectively after VZV infection；In addition，168 h after VZV infection，the level of DNA replication and the titer of VZV increased by 5. 7 folds and 4 folds respectively. Conclusion The successful establishment of MRC⁃5IFNAR1⁃ cell line may be a potential scheme to increase the yield of vaccines based on human diploid cells，and provided a reference for expanding production of VZV vaccine.

Glucose monitoring is an important part of medical care in diabetes mellitus, which not only helps assess glycemic control and treatment safety, but also assists with treatment adjustment. With the development of continuous glucose monitoring (CGM), the use of CGM has increased rapidly. With the wealth of glucose data produced by CGM, new metrics are greatly needed to optimally evaluate glucose status and guide the treatment. One of the parameters that CGM provides, time in range (TIR), has been recognized as a key metric by the international consensus. Before the adoption of TIR in clinical practice, several issues including the minimum length of CGM use, the setting of the target range, and individualized TIR goals are summarized. Additionally, we discussed the mounting evidence supporting the association between TIR and diabetes-related outcomes. As a novel glucose metric, it is of interest to compare TIR with other conventional glucose markers such as glycated hemoglobin A1c. It is anticipated that the use of TIR may provide further information on the quality of glucose control and lead to improved diabetes management.

ObjectiveTo explore medication regularity of traditional Chinese medicine （TCM） in the treatment of non-small cell lung cancer （NSCLC） and thereby to lay a theoretical basis for clinical medication and drug development. MethodArticles on clinical treatment of intermediate and advanced NSCLC with TCM in the past 40 years were retrieved from CNKI， which were taken the data source. Then the articles were screened to establish a formula database， followed by frequency statistics， association rule analysis， cluster analysis， factor analysis， and complex network construction. ResultA total of 307 eligible articles were screened out， involving 483 formulas. The common syndrome of intermediate and advanced NSCLC was the deficiency of both Qi and Yin， with the common syndrome elements of Qi deficiency， Yin deficiency， phlegm， blood stasis， pathogenic heat （fire）， toxin， and pathogenic dampness. The frequently used medicinals mainly had the functions of tonifying deficiency， clearing heat， resolving phlegm and relieving cough and dyspnea， promoting urination and draining dampness， and activating blood and resolving stasis. The high-frequency medicinals were Astragali Radix， Glycyrrhizae Radix et Rhizome， Ophiopogonis Radix， Fritillariae Thunbergii Bulbus， and Poria， which were mainly cold， bitter， sweet， and pungent， with tropism at lung， spleen， and stomach. The association rule analysis yielded 17 rules with strong association. Ten common factors were extracted from the factor analysis， and cluster analysis classified the medicinals into 5 groups. Complex network analysis suggested that the core formula was modified Liujunzi Tang and Yiqi Yangyin Jiedu prescription. ConclusionThe treatment principle for intermediate and advanced NSCLC is replenishing Qi and nourishing Yin， invigorating spleen and resolving phlegm， clearing heat and detoxifying， promoting blood circulation and removing blood stasis. The core combinations new prescription discovered by data mining are of important guiding significance， but they should be further verified in clinical practice and by experiments based on the theory of TCM.

Epilepsy is a brain condition characterized by the recurrence of unprovoked seizures. Recent studies have shown that complement component 3 (C3) aggravate the neuronal injury in epilepsy. And our previous studies revealed that TRPV1 (transient receptor potential vanilloid type 1) is involved in epilepsy. Whether complement C3 regulation of neuronal injury is related to the activation of TRPV1 during epilepsy is not fully understood. We found that in a mouse model of status epilepticus (SE), complement C3 derived from astrocytes was increased and aggravated neuronal injury, and that TRPV1-knockout rescued neurons from the injury induced by complement C3. Circular RNAs are abundant in the brain, and the reduction of circRad52 caused by complement C3 promoted the expression of TRPV1 and exacerbated neuronal injury. Mechanistically, disorders of neuron–glia interaction mediated by the C3–TRPV1 signaling pathway may be important for the induction of neuronal injury. This study provides support for the hypothesis that the C3–TRPV1 pathway is involved in the prevention and treatment of neuronal injury and cognitive disorders.

Objective: To evaluate the safety and clinical efficiency of holmium laser enucleation of the prostate (HoLEP) in the treatment of small-volume BPH (SBPH) complicated by severe lower urinary tract symptoms (LUTS). METHODS: We retrospectively analyzed the clinical data on 82 cases of SBPH with severe LUTS treated by HoLEP from January 2017 to December 2018. The patients were aged (65.5 ± 7.6) years, with a mean prostate volume of <40 ml, a total IPSS of 24.8 ± 4.6, a QOL score of 5.2 ± 0.8, the maximum urinary flow rate (Qmax) of (7.6 ± 3.7) ml/s, and a mean PSA level of (1.8 ± 1.4) μg/L. RESULTS: All the operations were successfully completed, the mean operation time averaging (30.2 ± 5.0) min, enucleation time (26.7 ± 5.6) min and comminution time (3.5 ± 1.1) min, and the enucleated tissue weighing (20.3 ± 4.9) g. After surgery, the bladders were irrigated for (3.5 ± 1.9) h, with (3.0 ± 1.7) L of rinse solution, and catheterization lasted (24.8 ± 9.7) h. Histopathology revealed moderate or severe lymphocytic infiltration in 69 cases (84.1%). At 6 months after operation, significant improvement was observed in the IPSS, QOL, Qmax and PSA level compared with the baseline (P < 0.05). To date, no urethral stricture-related reoperation was ever necessitated. CONCLUSIONS HoLEP is safe and effective for the treatment of SBPH complicated by severe LUTS and can be employed after adequate preoperative evaluation of the patient.《.
